Syracuse, NY - Just days before he was scheduled to go to trial, Mark McMullen decided to plead guilty to second-degree murder.

The 22-year-old Syracuse man admitted in Onondaga County Court that he shot and killed Miquan Lawrence on April 6, 2012.

Lawrence, 18, was crossing the street toward the Green Ale Market on East Fayette Street about 6:30 p.m. when he was hit four times by gunshots from in front of the store, according to court papers.

Lawrence ran across the street, then collapsed. Police found him at a parking lot at 171 Croly St., unconscious and with gunshot wounds to his torso and lower abdomen, police said. He was taken by ambulance to Upstate University Hospital, where he was pronounced dead.

A week after the shooting, McMullen turned himself in. He was promised a sentence in court on Wednesday of 18 years to life in prison in exchange for his plea.

If he had been convicted after his trial, which was scheduled for next week, McMullen would have faced 25 years to life in prison on the second-degree murder charge, with an additional 15 years on a weapons charge.
